SELVAGlE-FORMING DEVICE.

SPECIFICATIN forming pari-of Letters Patent No. 237,087, dated February1, 188.1. Application tiled July 21, 1880. (No model.)

To all 'whom it may concern:

Be it known that'I, WILLIAM A. BRICKLLL, of Belleville, of "New Jersey,have invented a new anduseful Improvement in Devices for Forming theSelvage of Wire-Cloth and Analogous Mate rials, of which the followingis a specification.

' In the accompanying drawings, in which similar letters of referencedesignate like parts, Figure l is a plan of a portion of a loom and ofmy new device thereon. Fig. 2 is a front elevation of the same. Fig. 3is a side elevation of the parts of my new device on an enlarged scale,and Fig. 4 is an end elevation of a portion of Fig. 3.

ais the hand-rail of the lay, beneath which is the reed, and with whichit is moved backward and forward from and to the line of the wovenfabric at every iiight of the shuttle. Attached to the side of thisrail, facing the position of the'operator, and near each end thereof, isa wedge or inclined-plane shaped cam, m, preferably of metal.

b is-the breast-beam-of the loom, attached to which near each endthereof, and opposite the cams already described, is aframe, cl,hav inga base, c, in which are formed slots to receive a bolt or bolts forconvenience of adjustment on the beam, and provided with bearin gs o andp, in which rests a rod, f, adapted t0 partially revolve in and slidethrough them to a limited extent. This rod j' is provided with a rigidly-attached arm, e, a spring, c', and a hook, g. The arm e is curvedor bent over, as shown in Figs.V l, 3, and 4, and its free end isbeveled or cut diagonally through in a plane perpendicular to the rodj'. Astop,q, Fig. 4,isformed at thelower end of this arm at the side ofthe rod j', and the spring t' is wound around this 4rod loosely, and hasits rear end attached to or resting against the frame d and its forwardend attached to the rod or resting against the arm e. I

Securedby the screw h in` that end of the rodf that is beneath itscurved arm e is a hook,

t g, the shaft of which is bent laterally at an angle of aboutforty-five degrees to the rod j', and its free end is bent down at rightangles to its shaft, as shown in Figs. 3 and 4.

In the drawings my devices are shown arranged for use only at that endof the loom in the county of Essex vand State that would be at the rightof the operative when at work. For use at the other end of the loom itwill be readily understood that the cam m, beveled end r of the arm e,stop q, spring t, and lateral bend of the shaft of the hook g must allbe reversed.

When the loom is at rest and the cams m and r not in contact with eachother, as seen in Fig. 3, the spring fi, by its resistance to uncoiling,holds the stop g securely upon its bed on the frame d, and by itsresistance to longitudinal compression holds the rod f forward in itsbearings, as shown in Figs. 3 and 4. The cam m and rod f must be soadjusted relative to each other upon their respective supports that thebeveled faces of the cam and of the arm e will engage with each otherwhen the forward movement of the lay carries the forward end of the camm into the perpendicular plane of the beveled face r. Provision forlateral adjustment for this purpose is made by the bolt andslots abovementioned.

From the position above indicated the further progress of the lay towardthe breastbeam brings the beveled face of the cam m hard against thebeveled face r of the arm e, and as the former is rigidly affixed to thehand-rail, while the latter is held in position4 only by the action ofthe spring i and the bearings o and p of the rod f, the arm c yieldslaterally under the pressure, its beveled face r sliding readily overthe beveled face of the cam m, whereby the rod f is caused to revolvepartially in its bearings, lifting the hook g above the surface ofthewoven fabric. While in this position the lay still continues to advanceuntil the edge or end ofthe arm e comes in contact with the base of thecam m, and then, as it moves on until the reed reaches the line of theWoven fabric, it forces back the rod f through its bearin gs,compressing the spring t until the lay has reached the farthest limit ofits forward travel, and then as it recedes the rod f follows, impelledby the spring i, until the base of the armc comes in contact with thebearing o, when the beveled faces begin to disengage and the spring t'to operate to forcethe arm over again into its position of rest, whichis attained when the beveled faces have become fully disengaged.

Starting from the relative positions of the Mib ICG

parts, as shown in Figs. l and 2 of the drawl ings, the operation may hefurther described as follows: The cam-faces being engaged, as shown inFig. 1, the hook is lifted froni the Woven fabric, the hook at the endof the loom (not shown) having done service during the last Hight oftheshuttle, and the hook shown having done no service during that iiight,the shuttle is at rest in the shuttle-box, (shown at k,) the layadvances a little farther, forcing back the rodfout ot' the way of theadvancing reed, which drives into place the thread that followed thelast Hight ot' the shuttle, and then the lay rccedes, disengaging thecams, the spring i, by its action on the bar f, restores both it and itsarm c to their position of rest, as above described, the stop qpreventing the hook from being` thrown too far over by the spring,thereby leaving the hook in position (preferably beyond the tirstwarp-thread) to catch and hold the bight of the filling that an yinstant later is formed by the Hight of theI shuttle to the other endofthe loom.

It will be readily understood that other springsniay be substituted forthe spiral spring shown, and the forms of the parts described may beconsiderably modified without departing from my invention but the spiralspring is cheap and durable, and in it and the other parts ot' thedevice I have shown and described what, after much experimenting, I havefound to possess in the greatest degree the necessary features to itssuccessful operation.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patcnt- The cani m, adapted to he secured to the hand-rail a,in combination with the frame d, adapted to he supported upon the beamb, and

the barf, provided with the spring i, hook g, 4o

and curved arm e, having the cam-shaped end r, all substantially asshown and described. WILLIAM A. BRICKILL. Witnesses:
